A team from The Shopping Center Group represented the tenant. Ross Spitalnick was the in-house landlord representative for Muss Development. Ariel Schuster and Brian Segall of RKF also represented the landlord.

The casual Mexican restaurant chain has five locations in Florida. This will be its first NYC outpost. The restaurant, located near the Barclays Center, spans the ground floor and a lower level and is expected to open by the end of the year. When it does, it will serve over 225 varieties of tequila and guacamole prepared tableside.

Messrs. Spitalnick, Schuster and Segall could not be reached for comment. Representatives from The Shopping Center Group did not return a request for comment.

The restaurant space at 339 Adams Street was previously occupied by a Morton’s Steakhouse, which closed last February on account of “shifting demographics” in the area. Muss also owns the nearby 345 Adams Street, which has recently signed with a slew of restaurant tenants. They include the fro-yo chain Orange Leaf , the sandwich purveyors Panera Bread and Potbelly, and Hill Country, an offshoot of the popular Murray Hill barbecue joint.

As of two months ago, 345 Adams Street was 100 percent leased.

“With the emergence of the Barclays Center and the overall evolution of Downtown Brooklyn, our space at 339 Adams Street made perfect sense for Rocco’s Tacos,” Jason Muss, a principal at Muss, said in a prepared statement. “They are popular in Florida and wanted to expand to New York City. They will be an excellent addition to the world-class dining options along the new Restaurant Row.”
